Returns the next representable value of from in the direction of to. If from equals to to, to is returned.
If from is finite, but the result of nextafter or nexttoward is infinite, raises FE_OVERFLOW and FE_INEXACT. If the result is subnormal or zero and from != to, raises FE_UNDERFLOW and FE_INEXACT. In any case, the returned value is independent of the current rounding mode.
